5.2 Rheometer Basic Instrument
5.2.1 Rheometer RHEOTEST ® RN with an automatic distance adjustment (Figure 1)
The rheometer (Figure 1) consists of a measuring drive (1), which is fastened by means of the knurled screw
(2) on the stand. The test drive is equipped with a quick coupling (3) for measuring systems like rotors, cones
or plates. With this quick coupling measurement systems can be changed quickly and easily.
The coupling (4) is used for fixing the adapter (6), for cone and plate measuring systems (or for fixing
measuring cups of cylinder measuring systems). The mechanism of the adapter is described in Adapter for a
Rheometer with an automatic distance adjustment. The coupling of the adapter or measuring cup is performed
by turn of the ball handle (5).
For measuring of samples, a Peltier-temperated basic plate (12) including located exchangeable plate (7) is
used. The basic plate is firmly connected with the basic plate guide (10). The basic plate guide is fixed by a
knurled screw (9) at the guidance rod of the stand. The stand (11) allows a stepless adjustment of the working
height of the measuring drive.
In the case of a device with an automatic distance adjustment, a two-sided temperature control of the sample
is carried out. The plate-plate distance setting is a part of the job to perform the measurements and is done
automatically.
